Boneco P500 Air Purifier (HEPA & Activated Carbon Filter)

How often do I need to replace the HEPA filter?

The combined HEPA and activated carbon filter should be replaced annually under normal usage conditions. The unit includes a filter life indicator that monitors usage and air quality to provide replacement reminders. Heavy usage in dusty environments or homes with multiple pets may require more frequent changes, typically every 8-10 months. Replacement filters cost approximately £100 and are available through authorised retailers.

What room size is the P500 most effective for?

The P500 is designed for rooms up to 720 square feet, which translates to approximately 67 square metres. For optimal performance, it works best in rooms between 20-50 square metres where it can achieve 4-5 air changes per hour. In smaller rooms, it will clean the air more frequently, whilst larger spaces may experience reduced air change rates but still benefit from continuous filtration.

How loud is the air purifier during operation?

The P500 operates at a maximum noise level of 64 dB, which is comparable to normal conversation volume. On lower fan settings, the noise drops significantly, making it suitable for bedrooms and quiet spaces. The Swiss-engineered motor and precision-balanced fan minimise vibration and operational noise. Most users report being able to sleep comfortably with the unit running on low or automatic mode.

Does the air quality sensor actually work effectively?

The built-in air quality sensor detects particulate matter and automatically adjusts fan speeds based on real-time air quality readings. LED indicators on the front panel display current air quality levels through colour-coded lights. The sensor responds to cooking smoke, dust disturbance and outdoor pollution entering through windows. Users report noticeable changes in fan speed when activities like vacuuming or cooking occur nearby.

Can I use essential oils with this air purifier?

Yes, the P500 includes a dedicated aromatherapy compartment for essential oils. The compartment is small and located within the unit's air circulation path. Add a few drops of your preferred essential oil to the designated area and the airflow will distribute the scent throughout the room. Be careful not to overfill or spill oil on other components, as this can cause the compartment to stick or affect performance.

Is the P500 energy efficient for continuous operation?

The unit consumes just 34 watts of power, making it economical for 24/7 operation. Running continuously costs approximately £2-3 per month in electricity at average UK rates. The automatic mode further reduces energy consumption by adjusting fan speeds based on air quality, running at lower speeds when air is clean. Energy Star certification confirms its efficiency compared to similar air purification systems.

How do I clean and maintain the pre-filter?

The washable pre-filter captures larger particles before they reach the main HEPA filter, extending its lifespan. Remove the front panel and gently vacuum the pre-filter monthly, or rinse with cool water for deeper cleaning. Allow it to dry completely before reinstalling. Regular pre-filter maintenance prevents larger debris from clogging the expensive HEPA filter, maximising the annual filter life and maintaining optimal airflow.

What's the difference between automatic and manual modes?

Automatic mode uses the air quality sensor to adjust fan speeds dynamically based on detected pollution levels. The unit increases speed when air quality drops and reduces to energy-saving levels when air is clean. Manual mode allows you to set specific fan speeds regardless of air quality readings. Most users prefer automatic mode for hands-off operation, switching to manual only when they want consistent high-speed operation or very quiet low-speed running.
